"""An image of a graph. The x axis runs from -3 to 3 and the y axis runs from 0 to 4. The graph is of four functions. The first function is """"f(x) = 2 to the power of x"""", an increasing curved function, which starts slightly above the x axis and begins increasing. The second function is """"f(x) = 4 to the power of x"""", an increasing curved function, which starts slightly above the x axis and begins increasing rapidly, more rapidly than the first function. The third function is """"f(x) = (1/2) to the power of x"""", a decreasing curved function with decreases until it gets close to the x axis without touching it. The third function is """"f(x) = (1/4) to the power of x"""", a decreasing curved function with decreases until it gets close to the x axis without touching it. It decrases at a faster rate than the third function."""
